01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper or foil and set a wire rack on top.
02 - Pat chicken wings dry with paper towels. Place in a large bowl. Add olive oil, salt, black pepper, garlic powder, and smoked paprika. Toss until evenly coated.
03 - Arrange wings in a single layer on the prepared rack. Bake for 35-40 minutes, flipping halfway through, until golden and crispy.
04 - While wings bake, combine ketchup, apple cider vinegar, brown sugar, Worcestershire sauce, Dijon mustard, smoked paprika, garlic powder, onion powder, and cayenne pepper in a small saucepan over medium heat. Simmer for 8-10 minutes, stirring occasionally, until slightly thickened. Adjust salt and pepper to taste.
05 - Transfer baked wings to a large bowl. Pour BBQ sauce over the wings and toss to coat evenly.
06 - Serve immediately, garnished with fresh parsley, alongside celery and carrot sticks if desired.
